SPECIFICATION forming part of Letters Patent No. 349,620 datedSeptembfifZl 1886,

Application filed July 28, 1886. Serial No. 209,274.

5 certain new and useful Improvements in Car- Starters, of which thefollowing is a specification.

This invention relates to a car-starter for street-cars, and isillustrated in the accomparo nying drawings, in which- Figure 1 is abottom or inverted plan view of a car and the starter. Fig. 2 is avertical longitudinal section on line y of Fig. 1. Fig. 3 is a partialside elevation showing the op- 1 posite side to .that seen in Fig. 2.Fig. at is a front or end view showing only the pawl-releasingmechanism. Fig. 5 is a top perspective view of the pawl-releasingmechanism detached from the car. Fig. 6 is a cross-seetion 20 of thecar, showing part of the mechanism on the line 2 of 1.

The letter A designates the car-body, and b the wheels. One wheel ormore is provided on its inner side with a ratchettooth rim, 0,

zg -preferably as large as the tread-face of the wheel, and a drafapawl,(l, engages with this ratchet. The mechanism which combines with theseparts, and-which constitutes this inven tion, will now bedescribed.

A lever, c, has on one end a sector-gear, c,

and is pivoted in a suitable hanger, f. The

other end of this lever is connected with the draw-bar G by a link, 71.The draw-bar has endwlse movement in bearings it. A spiral 3 5 spring, 1is about the shaft or pivot-bolt j of the said lever e, and is connectedtherewith in such way that its tension is exerted to throw the link endof the lever back, and

- thereby draw the draw-bar G, as seenin Fig. 0 1.

The parts will occupy this position normallythat is, when the car is atrestand when the animals start to pull the spring i will yield and thedraw-bar G will be drawn out, which action brings the draft-pawl d to 45bear on the ratchet-rim c, as hereinafter described, and thereby startthe car. A crankshaft, k, has at one end a pinion, Z, which engages withthesector-gear e on the lever 6, while its crank it is connected withthe draft (No model.)

with its sector-gear 0, causes the crank-shaft 7.: to rock or partlyrevolve, and the throw thus given the crank imparts movement to thedraitpawl.

Two crank-stops, q, are fixed to the car,

one each side of the crank h. These, by arresting the throw of thecrank, limit the movein ent of the draft-pawl (Z.

Two pawl-releasers, n and a, each have one end pivoted to different endsof a three prongcd lever, 0. The other end of each pawlreleaser has anincline, d, which takes under the pawl (1. One prong of the lever 0 iscon neeted by a rod, 9, with the sector-gear lever '0. (See Fig. 1.)When the draft-pawl d is brought to bear on the ratchet-rim c by a pullon the draw-bar G, and just as it has completed its forward movement,the inclined end (1 of the pawl-releaser a is pushed below thedraft-pawl d, and by raising the said pawl serves to release itsengagement from the ratchet-rim c, and as long "as the draw-bar G iskept pulled out this releaser n will continue to keep the draft-pawlraised and out of contact with the ratchet-rim, whereby the carwheel I)will turn without the draftpawl producing a clicking noise. WVhen thereis no pull on the draw-bar G, the spring 1' will cause the draft-pawl dto recede to the position shown in Fig. 2, and then the 1 )awl-releasern will. raise the draft-pawl. from the ratchet-rim.

,- and allow the ear to be backed.

This car-starter will, on street-railways that are level, enable oneanimal to do the work 9 a lever, e, having one end connected to thedraw-bar and provided with sector-gear e, a shaft, k, having at one enda pinion, Z, engaging with the sector-gear, and provided at the 50 pawld. It will thus be seen that the lever 0, other end with a crank, k,connected with the neeting the three n'enged lever with The said IOlever e, as shown and described.

In testimony whereof I affix my signature in, the presence 01" twoWitnesses.
